ROTARY CLEALN'SER.

To all whom t may concern.'

Be it known that I, WILLIAM L. DEMING, a citizen of the United States,residing at Salem, in the county of Columbiana and State of Ohio, haveinvented a certain new and useful Improvement in Rotary Cleansers, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention relates to a machine for 'washing such articlesv asdishes, cooking utensils, knives,A forks, etc.

The general object of the invention is to provide ,such a machine whichmay be cheaply manufactured, simple in construction and very convenientto operate.

In carrying out my invention -I provide a rotary receptacle for thearticlesl to be cleansed, mounted within a stationary casing and havingmeans whereby a stream of water may rotate the receptacle, and Ialsoprovide means for spraying cleansing liquidonto the articles to becleaned whileithey are revolved in the receptacle. A. more specieobject. of the invention is to so arrange the device that the dishes andother articles may be very conveniently placed in p0- sition in thereceptacle so that it may be balanced and rotate evenly. A furtherobject is to provide means controlling the cleansing water or otherliquid and the water for rotating the receptacle, which, by operating asingle member through a series of steps, may first wash the dishes withwater and soap or other cleansing liquid, then rinse the same, whilerotating the container, causing the air to dry the dishes after whichthe further movement of such member acts to discontinue the rotation.

My invention is hereinafter more fully described in connection with thedrawings, and other-objects will become apparent in such description.The essential characteristics are summarized in the claims.

the operation of the cleanser. These sections are taken substantially onthe line 7-7 of Fig. 5; Fig. 10 is a similar section through the lowerportion of the valve ydevice, taken substantially on the line 1010 ofFig. 5; and Fig. 1l is a plan of the controlling device.

Referring to the drawings by numerals, .l indicates a substantiallycylindrical casing shown as having a closed bottom 2, preferablyslanting toward a draining opening,

shown as Vfitted with Va suitable screen v3 \be low which is a suitablewaste passage 4. The casing 1 is shown as mounted on legs 5 which may beof any suitable construction. This casing' is preferably made of lightsheet metal, andv has vits upper edge curved. in-l j wardly overareinforcing ring, as indicated at 7. Fitted; over. the upper'edge ofthe cas-A ing 1 is preferably provided an upwardly curved. ordome-shaped cover 10 having a embracing the upper edge of the casing.

Extending transversely `across the casing I have shown a bridge member12 having its ends curved around the bead portion 7 and secured to thesides of the casing 1 at 14 by rivets or any suitable means. This bridgemember carries a hollow ball bearing member l5 in which I provided anannular series of balls 16 adapted to engage the lsides of a verticalshaft. 17 and the under side of an annular flange or shoulder 18 rigidwith the shaft. This shaft preferably eX- tends upwardly through thebridge member and may be provided with any suitable knob or rotatingmeans, for lexample I have shown a crank 20. The lower end of this shaftis Iguided by an upwardly extending projection 22 rigidly secured to thebottom 2 and fitting a corresponding bore in the lower end of the shaft17. This'shaft carries the receptacle for the articles to be cleansed,and it will be noted that the weight -is entirely supported on the balls1G. the lower end of the shaft merely being positioned by theprojection. 'f

The receptacle for the dishes preferably comprises a substantiallyhorizontal plate member 25 secured and supported by' a spider26'surrounding the lower end of the shaft 17fand rigid therewith. Thisplate 25, which is preferably of sheet metal, extends outwardly to apointadjacent but separate from the cylindrical walls 1 of the casing,

"downwardly extending flange portion 11 and rising from its peripheryisy a substantially cylindrical wall of woven wire, indicated at 28 andstrengthened vat its upper end by a ring 30. Thus the plate and the wirewall 28 form, in eii'ect, a basketv rotatably mounted on the shaft 17.The ring 30 1s preferably braced by a transverse rod 31 secured at itsends-to offset portions 32 in the ring 30 and bound to the shaft 17 atits intermediate point. Depending from the transverse rod 31 areradially arranged vertical walls of open wire mesh dividing the basketinto two compartments and form- `ing walls against which articles to becleansed may bey rested or leaned. Toprovide for loading the twocompartments of the basket receptacle with dishes so that the weight onopposite sides of the shaft may be substantially equal,I provide tworadially arranged vertical walls 34 made of open l wire weave andsecured to a U-shaped wire having its opposite ends rotatably embracingthe shaft 17, as indicated at 36. The loops aroundthe shafts of the twomovable walls rest one upon the other, and the lower loops restupon'suitable collars, indicated at 37.' These walls maybe swung aboutthe shaft 17 and are secured in any desired position by hooks 38, shownas secured throughclips 39 at the'upper portion ofthe wall and adaptedto extend over and embrace the ring 30. j N

In leaning thedishes against the wall 31,

it is desirable to provide projections eXtending- Iupwardly from theplate 25 against which the edges of the dishes may rest to prevent`their displacement. This I accomplish by turning upwardly tongues `41inte-` gral with the metal of the plate, thus leaving openings 40through which water may drain while the dishes are being washed andrinsed. In placing the dishes in position it is desirable to begin byleaning them against the wall 31 and then one against the other at oneside of the receptacle and then placing others at the opposite sides o fthe rece tacle until the weight is vsubstantially even y divided. Thento prevent displacement of the dishes, the walls 34 are swung towardthe, dishes and secured in position by the hooks 38.

The rotation of the basket receptacle is accom lished by providing, onthe lower side o the plate 25 a'djacent its periphery, downward bladesso faced that they may receive water 1n their concave side, projectedExtending inwardly from another portion of thel valve 50 is a tube v52,having on itsA inner end, Ia nozzle 53, standing substantially midway ofthe height of the wall 28 vand adapted to project a cone-shaped sprayinwardly against articles carried by the receptacle. Rlsing from thetube 52, adjacent the nozzle 53 is a pipe 55 which is curved-` inwardlyand lies along the under side of the bridge 12 at 56,.being secured by asuitable clip 57. The portion 56 of this tube is f provided with aseries of openings 58 on its under side adapted to project'small streamsdownwardly to the articles in the receptacle. At 60 is indicated acontainer for liquid soap or the like from whicha tube 62 leads tothecontrolling device 50 where such liquid may be mixed withthe waterprojectf ed from the nozzle 53 and tube 60, depending upon the positionofthe operating member 65 for the valve device 50.

rThis controlling device is adapted in preferred form to direct hotwater and soap onto the articles in the receptacle lirst, while at thesame time directing water to the projections underneath the receptaclewhereby 1t is rotated, then shut off the soap directing hot water to thedishes while the receptacle rotates, and then close olf the hot waterwhileV rotating only, whereby the dishes may be dried by such rotation.The

form of this controlling device illustrated in the drawings,'will now bedescribed.

Referring to Figs. 5 to 11, 70 indicates a `casing or body of thecontrolling valve 50, shown as 4provided with a lvertical. taperedvopening into which is rotatably fitted a plug 72 having an upwardextension 73 rigidly carrying the handle 65; extension is a ring ofsuitable packing mate- Surrounding the.y

rial 75, inclosed in a cap member 76 threaded onto the upper'end of thecasing. Leadingtransversely toward the plug 72 is a hot water passage 77to which water is led through' a suitable pipe 78 threaded into thecasing, as shown. Water flowing through the passage 77 enters asector-shaped opening communicating with an axial passage 80, v

leading downwardly to an exit passage 82 through which water lmay yflowto the pipe 52 and nozzle 53. This pipe 78, I prefer to use for hotwater.

In the side of the body 70, opposite the` pipe 78, is a small pipe 62leading from the liquid soap receptacle 60 under the control of a cock63. This pipe communicates with a short passage adapted to register witha" groove 83 formed in the surface of the plug -70 and extendingdownwardly to a short passage 84 communicating with the exit passage forthe hot water. To cause the soap to be drawn downwardly through thesepassages, I provide a short curved tube 85 having a contracted endopening toward the direction in which the water is iowing and I leadingdownwardly to an opening in the lower end of the stem 7 0 which receivesthe threaded end of a pipe 91 leading to the pipe 46 which as heretoforestated, leads water to the nozzle for rotating the basket receptacle.

The operation of this valve controlling device is as follows: With thehandle 65 in the position shown in Figs. 5 and 6, the plug presentssurfaces closing the passages 77, 83 and 89, and on turning the valve inthe direction of the arrow in Figs. 7 to 9 and 11, a short distance, forexample, one-eighth of a turn, the. sector-shaped openingsl of thepassages 80 and 90 are brought opposite the passages v7 7 and 89respectively, thus allowing hot water to pass through the pipe 7,8throiigh the plug and pipe 52 to the interior of the casin where 1t isJforcibly thrown against the dishes. This first movement also brings thegroove 83' into position to allow soar to pass downwardlyfrom the tube62 to t e short tube 85 and mix with the water vthrown against thearticles-to be cleaned.

With the valve in this samey position the sector-shaped opening of thepassage 90 registers with theo ening 89, thus allowin water (preferablycdid) to pass through t e pipe 88, passage'90' and pipe 91 to thenozzle45, wherel it is thrown against the'blades lllA on the under sideof the receptacle, thereby acting to rotate this receptacle,whilethe hotwater mixed with soap, or othery cleansing j fluid, is thrown againstthe articles' to be cleaned and these articles are revolved withf in theeasing presenting all surfaces to the streams of water thrown onto thesame. The

cleaning water passes outwardly through the open sides of the basket anddownwardly through the openings 41 and is drained off Vthrough thedraining opening in the bottom of the casing.

The above operation is continued long enough to thoroughly cleansethedishes andl they maybe rinsed by turning the handle 65 another stepin the same direction, thus 'bringing the groove 83 out 'of registrationwith the' passages for the soap thereby -closing the same while thesector-shaped openingsfor the hot and cold water still remain inregistration with-the corresponding pas? sages, thus hot water is thrownupon the dishes which still continue to revolve. The position of the lugunder the two conditions described, is shown in the sections in Figs. 7and 8. It will be noted that in the firstl (Fig.` 7) the groove 83 is inregistration with the soa passages and in Fig. 8 it is lbrought out oregistration while the hot water passage. still remains incommunication.

A' still lfurther movement of the handle brings the sector-shapedopening for the hot water passage out of registration with the passage77 and also the passage 82 thereby stopping the flow of -hot water (thisposition is indicated vin F ig.v 9) but the opening for the cold water,extending through more degrees of the surface of the plug, may stillremainin registration with the passage 89, thus the lcold water maycontinue to revolve the receptacle drying the dishes by the tendencyl ofcentrifugal force to throw the ing performed when a valveis in a certainposition,`for example, in Fig. 11, the indicator stands over a marklabeled dry, meaning that the cold water only is passing through thevalve which is acting to rotate the'receptacle causing the dishes to bedried,

as. above described.v

To prevent the operations'taking place in reverse order or out of ord rby inadvertently turning the handle in t' ewrong direc-- tionI mayprovide notches 97 inthe shank 73 of the plug and which may be engagedby a pawl 98 pivoted to the top of the oa'p and actuated by a spring 99.These notches are preferably so yarranged that each notch .maycorrespond to an operation so that it is, not necessary rto observeclosely the posit-ion of the indicator, but to perform the completeoperation, one need only move the handle so that each notch i'ssuccessively engaged by the pawl. The click of the pawl `indicates thehandle has been brought to proper position for the next operation. In

' ,the particular form of valve shown, the

movement of the handle required for the several operations is materiallyless than the entire revolution, but the pawl prevents the handlepassing in the wrong direction and the surfaces are so arranged that thevalve remains closed from the time it is first shut oi' until it isbrought around to the first operating position.

Economy of cold water may be effected by rotating the receptaclemanually by means V'of the crank 2O and ,this handle is also useful .inconnection with the motor. The starting of the rotation'may be hastenedby the use of the crank. This may'sometimes be necessary when thereceptacle is heavily loaded. In the top of the cover is indicated anopening 100 of a size adapted to pass freely over the crank irrespectiveof its position. This opening may permit the circulation of air over thedishes during the drying operation. Air entering through this openingmay pass outwardly through a tangentially arranged passage 102 shown asclosed by a pivoted cover 103 extending across the open end of thispassage. It will be seen that as the dishes Within the receptacle arebeing rotated after the hot water is shut oft air will be caused tocirculate rapidly and will enter through the opening 100 and be forcedVoutwardly something after the manner of a blower through the opening102 when the cover 103 is raised, as indicated in Fig. 1. Thus a veryfree circulation of the air is permitted over the dishes which, beingheated by the hot water, tend to dry very quickly.

After the dishes are completely dried, as described by the aboveoperation, 4the cover 10 may be removed, a suitable handle beingprovided at 105, thus allowing free access to the interior for removalof the articles'.
